OpenConstructionERP brings estimating, tendering and project control into one construction platform. Its BOQ structure handles positions, resources, assemblies and automatic markups, while quantity extraction works with RVT, IFC, DWG and DGN files through DDC converters. Scheduling includes Gantt planning, CPM, Earned Value Management, S-curves and Monte Carlo simulation. A REST API, Excel/CSV/GAEB XML exchange and self-hosted deployment support customized workflows and local data control. The free self-hosted plan includes the full platform, while cost databases, converters, implementation and support services can add charges.
Alternatives can make more sense for residential building, focused PDF takeoff, mobile crews, infrastructure models or accounting-connected workflows. OpenConstructionERP has no accounting integrations, and its documented desktop support is Windows 10/11, macOS 10.15+ on Apple Silicon and 64-bit Linux, alongside web access. Compare whether you need narrower estimating tools, cloud collaboration, mobile updates, specialized model coordination or business-management modules. Also check each option's device coverage, data-control approach, free-plan limits, trial terms and paid additions before moving work away from OpenConstructionERP.
